They say home is where the heart is. Because we spend so much time at home, the heart of the home
should therefore be as healthy as possible for your whole family. Clean, fresh air is paramount to good
health and overall wellbeing.

current New Zealand Building Code. It also complies with the
Current building regulations now demand homes to be built
more airtight as they are subjected to higher insulation
standards. But the option of leaving doors or windows open to
allow more fresh air to enter is often not the solution from an
outdoor noise or security perspective.
Ventilation Standard NZS4303:1990 that specifically requires
ventilation systems to draw fresh air from the outside and not

System that brings in filtered fresh outdoor air to replace stale
The lack of natural ventilation due to airtight spaces can lead to
fluctuations when additional fresh air is introduced. This is
the build-up of moisture laden stale air within the home. This is
important as too many air changes will lead to dramatic drops in

indoor air. The optimum number of air changes are regulated
to ensure there are no draughts, whilst minimising temperature
respiratory problems. Furthermore, mould and dampness can
also compromise both building materials as well as furnishings
inside the home.
Common places for mould to grow
not only include window sills,
curtains and carpets, but also
walls and damp areas such as
laundries, kitchens and bathrooms.
Conventional positive pressure
ventilation systems are not designed
to deal with the additional moisture
load from these damp areas.
Maximise heat recovery even from damp areas
Because of its unique highly efficient heat recovery ability, the
system maximises recovery of the available heat energy from
outgoing stale air, as well as heat energy contained in moist air
from damp areas such as bathrooms, toilets and kitchens.
Pre-warm or cool air to save on your power bill
This recovered heat energy is then utilised to pre-warm
incoming air in winter or pre-cool this air in summer –
ultimately saving you on your heating or cooling bill. The end
result is a healthier, drier and warmer home.
The Mitsubishi Electric Lossnay Difference
What makes the Balanced Pressure Lossnay VL220 Heat Recovery Home Ventilation System from
Mitsubishi Electric so different from other systems is our advanced Diamond Lossnay Core at the heart
of the heat exchanger.
Unlike ordinary positive pressure ventilation systems, the
patented Diamond Core and built in drain outlet allows the

pre-warming in winter or pre-cooling in summer, rather than
going to waste by directly transferring this air outside. In doing
so, moisture build up in your home is minimised while healthy
humidity levels are maintained and managed.
The end result: your home is ventilated with fresh, filtered
and clean pre-warmed (or cooled) air at the same time whilst
maintaining optimum humidity levels for healthy living. The
system is super energy efficient and designed specifically to be
whisper quiet.
Why outside air, not attic air?
Not all air is created equal. Lossnay only draws fresh air from
the outside specifically – it does not draw air from the attic. The
absence of significant air movement common in attics means
the air is likely to be stale. In addition, build-up of dust, dirt and
other contaminants such as mould, insect and rodent droppings
makes this air much harder to filter before it is distributed
through your home. This is why the Balanced Pressure Lossnay
system specifically utilises direct fresh air instead.

How It Works
The Balanced Pressure Lossnay Heat Recovery Ventilation System removes stale, dirty air and draws
in fresh air from outside. Lossnay also recovers heat energy from the air being transferred to pre-warm
(or pre-cool) the fresh air being drawn into your home. The VL220 model is ideal for small to medium
sized homes between 52m2 and 192m2.
1. The stale air extracted from your home is Return Air (RA). Return
Air can contain high levels of CO2, odours and other pollutants.
This Return Air stream also contains heat energy that Lossnay
can recover, which is not the case with other positive pressure
ventilation systems.
2. As the stale Return Air is removed, Lossnay’s core ‘recovers’ the
useful heat energy from it. The air is then exhausted (EA) outside
along with the unwanted pollutants.
3. Outdoor Air (OA) is introduced to provide fresh clean air. It is first
filtered, then passed through the Lossnay core. This allows it be
pre-heated in winter (or pre-cooled in summer) using the energy
recovered from the Return Air.
4. Supply Air (SA) then enters your house as fresh pre-heated or
pre-cooled air.
EXTRACTS STALE AIR
Extracts stale air removing toxins and reducing
humidity.
SUPPLIES FRESH AIR
Supplies fresh air increasing the oxygen levels in
the home and assists with managing the build
up of moisture.
HEAT ENERGY RECOVERY
Recovers up to 86% of the heat energy from the
outgoing air to preheat the incoming air, saving
you money.

Balanced Pressure Heat Recovery Ventilation Benefits
Ventilating your home is vital as it maintains air quality and reduces moisture, creating a healthier and
more comfortable environment. The Mitsubishi Electric Lossnay System is a patented heat recovery
ventilation solution that uses fresh air (not attic air) to ventilate your home. The system works by
extracting stale air from inside your house and replacing it with allergen reduced fresh air from outside.
